Math Help Please.

WOW!! Just wow... and shame on some of the posters. OP, you asked for assistance on how to set it up? Yes, this is a true TWO step. It sucks. So write this down after me. Here we go:

Step 1: Find the conversion factor that you need.

- you need to do this by breaking down the "med rate ordered"

*3mcg/kg/min for an adult weighing 95.9 kg*

3mcg 95.9 kg

1 kg x 1 min

cross out the "kg" - they cancel each other out giving you:

3mcg x 95.9

1 1 min

Gives you 287.7mcg

1 min

THIS is the end of step 1. This is your "c" factor (conversion)

Step 2:

You're looking for mL/Hr = the best way that worked for many of my classmates & I is to set up the top value you're looking for. i/e - "mL" Let's do it together.

mL = 250mL 1mg 287.7mcg 60min

hr 400mg x 1000mcg x 1min x 1hr

cancel out all the "buddies" giving you this:

250mL x 1 x 287.7 x 60 4315500mL 10.78 = 10.8mL

400 x 1000 x 1 x1 = 400000hr = hr

your question was rounded to the tenth so voila'

Hope this helps. You can use this to work out the other one you were given as well. Good luck!

and the spacing STILL looks crazy.... sorry OP. Hopefully you can make some sense of it though

This is off-topic, but I would really like to know what school/state/country allows a student to not take ANY math class beyond ninth grade and beyond geometry. And also what nursing program requires NO math class as a prerequisite? Could this maybe have something to do with all the math difficulties I see students having on this site? Just an observation, not being judgmental. I was put through the ringer in high school and college math classes, and now, if what I'm reading is correct, math is not even a requirement?

My program required college level math at a minimum. No matter what level math you got to in Highschool. College math had basic stats/probability, algebra, a little geometry and something else. They also required chem either from highschool or taken in college. Both if those classes would show how to work these problems. It's sad that not all programs require at least basic college math as a requirement for entry to the program, see as med math can seem so complicated to those who didn't have to take anything. I took trig in highschool so college math was a cake walk, but that is not the case for everyone. GreenTea's breakdown in her second comment was fantastic if you don't know how to set up dimensional analysis since it broke the question down piece by piece. Our program uses Calculate with Confidence, which I thought explained both the formula methods and dimensional analysis method pretty well. I wish all schools required a math for entry and until this thread, I wasn't even aware that some schools didn't.

While math was not a requirement for my program, we did have to get above a 90 on our HESI which would assume that someone could pass basic middle school math.
